To describe the musculoskeletal adaptations inherent to the cricketers' shoulder and determine potential predictors of shoulder injury in elite South African cricketers.
Prospective longitudinal cohort study; SETTING: Non-clinical, at national cricket indoor training venues.
One hundred and six elite cricketers, representing 82% of the South African national and franchise teams, consent. A total of 105 cricketers (27 ± 4 years) were eligible for participation in this study.
A pre-season shoulder screening battery including a shoulder function questionnaire, two ultrasonographic shoulder measurements and 14 musculoskeletal tests including pain provocation, range of motion, strength and flexibility was assessed. Non-contact dominant shoulder injuries were documented throughout the 2016/2017 season.
The musculoskeletal profile of a cricketer's shoulder is described. 17% (95%CI: 9-24%) of cricketers sustained an injury during the 2016/2017 season. Two of the 17 screening tests predicted seasonal dominant shoulder injury (p < 0.05): a dominant supraspinatus tendon thickness ≥5.85 mm (sensitivity: 72%, specificity: 63%) and non-dominant pectoralis minor length ≤12.85 cm (sensitivity: 83%, specificity: 55%).
The musculoskeletal adaptations inherent to cricketing shoulders are distinctly different to the classic "thrower's shoulder" described in baseball. A thickened dominant supraspinatus tendon and a shortened non-dominant pectoralis minor muscle are risk factors for developing shoulder injury in this group. This identifies the need to investigate preventative strategies (strengthening/flexibility) and throwing workload management in cricketers with shoulder injury.
描述板球运动员肩部固有的肌肉骨骼适应性，并确定南非精英板球运动员肩部受伤的潜在预测因素。
前瞻性纵向队列研究；地点：国家板球室内训练场馆，非临床环境。
106 名精英板球运动员，代表南非国家和特许球队的 82%，同意参与。共有 105 名板球运动员（27±4 岁）符合参加本研究的条件。
在赛季前进行肩部筛查，包括肩部功能问卷、两项超声肩部测量和 14 项肌肉骨骼测试，包括疼痛诱发、活动范围、力量和柔韧性。在 2016/2017 赛季期间，记录了非接触性优势肩伤。
描述了板球运动员肩部的肌肉骨骼特征。在 2016/2017 赛季，17%（95%CI：9-24%）的板球运动员受伤。17 项筛查测试中有两项预测了季节性优势肩伤（p<0.05）：优势冈上肌腱厚度≥5.85mm（敏感性：72%，特异性：63%）和非优势胸小肌长度≤12.85cm（敏感性：83%，特异性：55%）。
板球运动员肩部固有的肌肉骨骼适应性与棒球中描述的典型“投手肩”明显不同。优势冈上肌腱增厚和非优势胸小肌缩短是该人群发生肩部损伤的危险因素。这表明需要研究预防策略（强化/柔韧性）和投球工作量管理，以预防肩部受伤的板球运动员。
